M'y'iinv'ention relatcsto a new and useful mechanism for positioning truck bodies,

carriers, skids and the like.

In devices of the character mentioned it is frequently desirable to adjust the hei ht I a'nd'position of the body of the device or more conveniently performing the work of loading or unloadingand the object of my invention is to provide a simple and convenient means for making the desired ad-- justment and elevation. I accomplish this object by the device illustrated in the accompanying drawings in which Figure 1 is a=perspective view of the device as applied to a portable belt conveyor truck.

Figure 2"is a plan view of the same. Figure 3 is a side view of a detail of the referred form of my operating gear and ocking lever. Figure 4 IS an end view of the same.

Similar characters of reference referito similar parts throughout the several views.

In the drawings I have shown the device applied to Ia portable belt, conveyor I truck body'l for the purpose of illustration but I do not intend to solimit my invention as it is apparent that my invention may be used to advantage with any form of device the inclination or adjustment of which it may be desirable to variably positionfincluding conveyors, trucks, bodies and the like.

I have also shown the device mounted on traction wheels 2 but the traction .wheels may be omitted ifdesired without departing from the spirit of my invention.

On shaft 3 which may be, if desired, the axle 'ca ing the traction wheels 2, I rovide a pair of rotatable collars4, 5, to w ich are respectively secured struts 6 and 7 e5;- tending from the collars 4 and 5 to collars 8 and 9 on a shaft 10 slidablymounted between the runners 10 adjacent the forward or delivery end of the truck body 1.

On the shaft 3 I also provide a pair of rotatable collars 11, 12 having struts 13 and 14 respectively extending therefrom to collars 13 1lres ectively on a rotatable Applicatlon'filed m 5, rear. Serial no. 724,301.

ally the delivery end and the lower end the rece ving en and I have so used these terms but it is apparent that the positions may be reversed or the bodymay be used in a horizontal position if desired.

On the shaft 10 I secure one or more winding cables-16, 17, which extend therefrom to the rotatable shaft 15 to which the cables are attached in any desired manner.-

On the rotatable shaft 15 I provide a geared driving wheel 18. A loose pinion 19 engaging the gear 18 is provided on a shaft 20 which may be carried by the strut 13.

The pinion 19 may be operated by means of a crank 21 and handle 22. This handle 22 may, if desired, be loosely mounted in the crank 21 so that it may be extended for. use as a hold for driving the pinion or it 'may be depressed and used for a locking means.-

As thebody 1 is supported by the struts 6, 7, 13, 14 it will be apparent that the elevation of the body 1-- will be varied according to the degree of the angle formed by the two pairs of struts.

The length of the cables 16, 17 will be such that when fully extended the truck body will be at its lowest desired elevation.

When it -is desired to elevate the truck body, the cables 16, 17 are wound on the shaft 15 by means of the handle 22, crank 21, pinion 19 and gear 18 until the desired elevation is attained, the handle 22 may then be depressed until it lies in the plane of the gear 18 and by engaging the gear 18 it will lock the pinion against rotation and securely fix the elevation of thedevice.

If desired, a dog 23 may be provided to engage and lock the pinion 19. i

It will thus be seen that any variation in the elevation 'or inclination on the truck body 1' within the limits of the cable 16, 17 may be easily and conveniently attained.

Having thus described my invention, what I claim is: v

1. In a device-of the character described a body, parallel longitudinal slots in said edges of said slots, a shaft transverse of .and 'slidable longitudinally along said slots on said runners, a; second shaft r ed insaid body, means to rotate said yoifinaled shaft, a Vshaped frame the ar ns of which may be moved with relation to one another, the ends of said frame being rotatably conpecte'd one arm to each said shaft, and means connecting saidishafts .whereby their relation may "be" varied. v

2. In a device ofthe -character descrlbed,

Q abodly, a shaft, a frame of parallel V mem hers ournaled on said shaft attheir apices and supportin'gseidbody, a second shaft journaled in the body and thru the end of one arm of said V, slots in the body having runners' therealeng, a third shaft journal in said body and slidable longitudinally of said'slots, said third shaft bemg also journaled in the end of the othera'rm of said V, and means connecting said second and third shafts whereby then relation to each other may be changed.

In testimony whereof, I, J1me L. WENTZ, have signed. my name to this specification, this 28 day of June, 1924. r
